Practicing your free motion quilting

I have taught free motion quilting for about 20 years. I meet up with former students and they tell me they have never really caught on to free motion quiting. I ask them how much they have done. The answer is anywhere from "tried once" to "a few times". Do you remember how many times you had to practice multiplication tables or practice when learning cursive writing? I try to convince people that their practice is like homework. To get better at something you have to practice it.
I think the "quilting police" have so many people intimidated that they won't even show their quiting, even if it is good, to someone else for fear of negative comments. I use the sample above and the one below to show that high contrast thread is going to show up and every stitch will show. The one below has matching thread and therefor creates texture rather than each individual stitch being important.
Are all of my stitches perfect? No, no, no. I don't let the quilting police into my home and I will accept my abilities, such as they are. I have been doing free motion work for 48 years. I don't have to prove anything to anyone else. You may look at these samples and say "48 years and she still isn't perfect". Perfection isn't what I am after. I am looking for acceptable and enjoyment.
I have been asked "What are these things?" meaning they are too big for a coaster, too small for a potholder. They are my practice pieces and I keep them around to remind me of ideas for designs,
to just generally brighten my day, to be a sample of certain threads, like the variegated thread in the sample below. I know people who won't create anything at all for fear of negative comments. We all need to support the creative talents of everyone, whatever their level of achievement and accentuate the positive.
